"[Science fiction] is the only kind of writing that allows you to look at the world we live in and change one piece at a time."
- Frederik Pohl

Oxygen Fountain  
  A small factory for making oxygen on the Martian surface.  

Making oxygen is the trick. Cracking water - hydrolysis - is comparatively easy; CO2 and oxidized dust take more energy and time. That's why we need fountains. Fountains are big, often the size of a semi cab... They plop down on the Red and if the dust is deep enough - if they're not on impenetrable hardpan - they burrow in and almost immediately pop out solar collectors and extraction vanes and whirl the vanes to collect moisture from the air.
